Scott Langholff, whatever you can do with a hardware based solution you can do with software - and often better. Yes, you can layer voices, edit voices, add effects and so on. In the end it is up to you and what you would like to accomplish. You need a good soundcard, a good computer (not the best), good software and good sound reproduction system. Once you are setup you will not return to hardware based solutions. Now it takes considerable effort to get it all setup initially but you will get a good return on your investment. I am an old man with limited mental capacity and did it. If I can do it most everybody else can do it as well - and better.
